"External commands disallowed while sourcing ebuild: ..."."

[rsa4046]

I hope this is not a stupid question, as it as been asked and answered previously, but I am wondering if the problem is the same. After

eix-sync && emerge -vaDNu world

and a successful sync I obtain,

These are the packages that would be merged, in order:

the "external commands disallowed ..." errors continue for quite awhile, similar to what is described in this post here.

However, the bug referenced (missing mozcoreconf-v5.eclass) is not seen in the above errors, and the emerge seems to otherwise complete successfully. Do I need to do anything?

provide full emerge output, please.

I am getting the same thing on 10 different machines.

AHA - I had a dependency nightmare, which I just managed to fudge my way around. After this I managed an update and those errors seem to have vanished.
